I'm having some trouble with using "case...esac" in Bash.
I've googled it and am stuggling to understand the syntax and how to do certain things.
Firstly, I want to be able to choose a case based on a variable number
For example, I have in my code a place where a user can enter a number using read.
Code:
read SEL
Then I want to use a case to decide what should be done.
I want it to be able to figure out whether it is a number or letter.
Using "if" you can always use
Code:
if [ $SEL -eq $SEL 2>/dev/null ]
then
echo "Is Number"
else
echo "Contains Letters or Symbols"
fi
I also want to have a case based on ranges of numbers too, but the upper range isn't a fixed number
So, in my code I find what the last number will be and define it as LASTNUM
In my case I want it be
Code:
case "$SEL"
0)
# Do Something for 0
;;
1-$LASTNUM)
# Do something for between 1 and LASTNUM
;;
Any variation of Q q or Quit)
# Do something for Q, q or Quit
;;
*)
# Do something for everything else
;;
esac
I've been really struggling and any help would be much appreciated.
It can get very annoying that bash regex =~ is case-sensetive, is there a way to set it to be case-insensetive?
if ]; then
echo match
else
echo no match

So what i am trying to do is write a script that takes in any number of scrambeled words and unscrambles them.
I have already addressed the issues of partial matches, exits silently if there are no matches, and finds words regardless of case that they were input. but while trying to get it so... (3 Replies)

locale::codes::langvar
Locale::Codes::LangVar(3pm) Perl Programmers Reference Guide Locale::Codes::LangVar(3pm)NAME
Locale::Codes::LangVar - standard codes for language variation identification
SYNOPSIS
use Locale::Codes::LangVar;
$lvar = code2langvar('acm'); # $lvar gets 'Mesopotamian Arabic'
$code = langvar2code('Mesopotamian Arabic'); # $code gets 'acm'
@codes = all_langvar_codes();
@names = all_langvar_names();
DESCRIPTION
The "Locale::Codes::LangVar" module provides access to standard codes used for identifying language variations, such as those as defined in
the IANA language registry.
Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
registry codes will be used.
SUPPORTED CODE SETS
There are several different code sets you can use for identifying language variations. A code set may be specified using either a name, or
a constant that is automatically exported by this module.
For example, the two are equivalent:
$lvar = code2langvar('en','alpha-2');
$lvar = code2langvar('en',LOCALE_CODE_ALPHA_2);
The codesets currently supported are:
alpha
This is the set of alphanumeric codes from the IANA language registry, such as 'arevela' for Eastern Armenian.
This code set is identified with the symbol "LOCALE_LANGVAR_ALPHA".
This is the default code set.
ROUTINES
code2langvar ( CODE [,CODESET] )
langvar2code ( NAME [,CODESET] )
langvar_code2code ( CODE ,CODESET ,CODESET2 )
all_langvar_codes ( [CODESET] )
all_langvar_names ( [CODESET] )
Locale::Codes::LangVar::rename_langvar ( CODE ,NEW_NAME [,CODESET] )
Locale::Codes::LangVar::add_langvar ( CODE ,NAME [,CODESET] )
Locale::Codes::LangVar::delete_langvar ( CODE [,CODESET] )
Locale::Codes::LangVar::add_langvar_alias ( NAME ,NEW_NAME )
Locale::Codes::LangVar::delete_langvar_alias ( NAME )
Locale::Codes::LangVar::rename_langvar_code ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangVar::add_langvar_code_alias ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangVar::delete_langvar_code_alias ( CODE [,CODESET] )
These routines are all documented in the Locale::Codes::API man page.
